I don't think they are either Majano or Palythoa, they both look quite different...
They kinda look like the ones in this thread, except for the color, mine are quite dull.

Anyway, I put some aiptasia X on them and they appear similar to zoanthids when closed. Unfortunately didn't have time to take pictures, but it looks like they took a pretty big hit.
